JET-CONDENSER.

Specification of Letters Patent. Pate t d pl 31 1921.

' Application filed September 18, 1919. Serial No. 324,624.

To all whom it may concern:

Be it known that I PAUL A. BANonL, a citizen of the United States, residing at Nutley, in the county of Essex and State of New Jersey have invented a certain new and useful Improvement in Jet-Condensers, of which the following is a specification.

This invention relates to a jet condenser of the low level type, and in particular to a low level condenser for condensing steam from power units having a condensate removal pump directly mounted thereon.

:The objects of the present invention are toprovide a compact and conveniently arranged condenser installation having a removal pump directly connected to its lower end and so mounted that it will be entirely supported by the walls of the condenser chamber and so arranged that the pump may be readily disassembled for inspection or repairs without removal of the pump body.

A further object of the invention is to provide a removal pump for a condenserinstallation supported from the condenser and adapted to be directly connected to a motor and having its pump bearings supported directly from the lower end of the condenser and chamber walls.

WVith these and other objects in view my invention consists in the features of construction and'operation set forth in the following specification;

In the drawings annexed hereto and formin apart of this specification:

I ignre 1 shows a view of the complete installation parts being shown in section.

Fig. 2, a side view of the complete installation.

Referring now more particularly to the figures of the drawing, 1 refers to a condenser chamber having a steam inlet 2 at its top, a water ring 3 surrounding the upper limits of the condenser chamber and a plurality of nozzles 42 distributed about this water ring adapted to throw jets of cooling water into the condenser chamber. At one side of the water ring 3 a water inlet 3 is provided adapted to be connected with any suitable source of cooling water. Within the condenser chamber 1 is a bailie or apron 5 adapted to guide the steam being condensed I and alsothe streams of falling'water, and at one side of the condenser chamber above the lower edge of the battle 5 is an outlet 6 to the vacuum pump for the air and non-condensables which may be conveniently connected to any form of vacuum or exhaust pump. Preferably the part of the condensing cham her 1 near the outlet 6 is divided off from the main portion of the chamber 1 by means of suitable projections provided on the baflle or apron 5. In order to cool the escaping air and non-condensables passing through this air chamber an extra nozzle 7 is located adjacent the outlet 6 so that an additional jet of cooling water may be sup plied to the air and escaping gases to cool them as much as possible before they reach the air pump. This may be connected to any convenient supply of cooling water at 8, or may be coupled by suitable piping with the water ring 3. 1 The condenser chamber 1 is adapted to be supported from a base plate or other foundation 9 by means of vertical rods or stays 10, any suitable number of these being used, the installation selected for illustration having four. l

The lower end of the condenser chamber is contracted in diameter and at its lower end is provided with, a flange 11 which may be suitably bolted or otherwise secured to the body member 12 of a pump having sufficient capacity to'remove the condensate and cooling water. Within the pump body 12 IS a suitable impeller of any suitable type having an impeller shaft 13 by means of and its shaft 13 to the pump body bracket members 16 are secured on either side of the pump body 12 by any suitable fastening means. These depend somewhat below the impeller shaft 13 and are suitably formed at the lower extremity to form thebearings 17.

As shown in the drawings the brackets take the form of open loops, the lower central portion of which is provided with the lower half of the bearing 17. Over the ends of the impeller shaft 13 cover plates 18 for the bearings 17 are also provided which may be readily removed in the usual manner.

Bolted or otherwise secured to the pump body 12 is a pump cover plate 20 which may be of the usual form, but as shown in the drawing when in operative position, assumes an inverted position. This cover plate 20 is provided with a conventional discharge volute 21 and joins a corresponding portion of the volute 22 in the body portion of the pump 12. At one side of the body member 12 is the discharge pipe 23 marking the termination of the discharge volutes 21 and 22.

It will be seen from the above description that should it be desired to disassemble the pump to examine or clean the impeller, it is only necessary to remove pump cover '20 which will permit a complete view of the in terior of the pump, and should it be necessary to remove the impeller for any purpose,

it would only be necessary to remove the brackets 16 after which the entire impeller and impeller shaft 13 may be lowered. In this way none of the pump discharge connections would have to be disturbed nor would it be necessary to remove anything but the pump casing 20. Furthermore the entire pump is supported. by means of the condenser supports 10 and requires no foun dation other than the supports and the walls of the condenser chamber.

The nozzles 4 may also be readily disassembled or removed from the condenser without disturbing any of the pipe connections. This is accomplished in the manner shown in Fig. 1. The outer wall of the water ring 3 is provided with holes one for each nozzle, these holes being of suitable size to admit the hands of a workman and suitably closed by caps 27. Preferably the nozzles 4 are threaded at their ends into the inner wall of the water ring 3 but it is obvious that any convenient method of fastening them in place may be employed. A rod 25 extends from the inner end of each nozzle 4 through the nozzle and through support 26 and also through the cap 27 where it is threaded and provided on the outside with a nut, thus permitting the rod to be drawn up or oosened slightly to adjust the spacer for the spray in the nozzles, to admit a larger or smaller amount of cooling water to the condenser chamber. The support member 26 is threaded to the rod 25 and, when the cap is drawn up on the rod 25, draws the support member 26 and cap 27 into engagement with the wall of the water ring 3.

It is to be understood that the present showing and description discloses only one specific embodiment of my present invention, and that other forms and modifications are included within the spirit and scope thereof, as expressed in the appended claims.

What I claim is:

1. In a condenser installation, a condenser, means in vertical alinement therewith for supporting the same, a condensing chamber, a condensate removal pump below said chamber in vertical axial alinement therewith and supported entirely by the walls of the chamber, said pump having a body portion joining the lower end of said chamber, an intake in which the flow is vertically downward and a side discharge, a pump cover plate separably secured to and depending from the body portion of sald pump and brackets supporting the impeller bearings, whereby the condenser installation is supported by the means supportmg the condenser.

2. In a condenser installation, a condenser, means in vertical alinement therewith for supporting the same, a condensing chamber, a condensate removal pump below said chamber in vertical alinement therewith and supported entirely by the walls thereof, said pump having a body portion joining the lower end of said chamber, an intake in which the flow is vertically downward and a side discharge, a pump'cover plate separately secured to and depending from the body portion of said pump and brackets secured on either side of the body portion supporting the impeller bearings, said brackets being in the form of open loops, whereby the entire installation is supported by the means supporting the condenser.

3.
